Apple Watch Ultra 4's Water Rating Is Three Separate Certifications, Not One Number
Apple’s spec sheet groups Apple Watch Ultra 4’s water resistance under one heading, but it is three separate certifications, not one number.

'Coming Later This Year' and 'a Future Software Update': Apple's Dating Language for Six Features, Decoded
Apple’s own pages date six features from this launch with one of four phrases: ‘later this year,’ ‘later in 2026,’ ‘coming late 2026,’ or ‘a future software update.’ None of the four names a month, and one names no year at all.
